UNITED STATES PATENT OFFICE,

HYDRAULIC MOTOR.

Specification of Letters Patent.

Patented July 9., I190'?.

Application led April 13,1905. Renewed December 14,1906. Serial N0- 347.881.

To all whom it may concern:

Be it known that I, GEORGE MoNo LYNCH, a citizen of the United States, residing at the city of Los Angeles, in the county of Les Angeles and State of California, have invented new and useful Improvements in Hydraulic Motors, of which the following is a specification.

This invention is a hydraulic motor, designed to utilize the buoyant qualities of a series or battery of floats, to compress air or otherwise generate power.

It is known that the buoyancy of a float does not depend upon its being surrounded by a large body of water, hence under proper conditions a small body of water may be utilized to take advantage of the buoyant quality of the float.

This invention includes a series of such floats, contained in tanks, to which water will be supplied and from which it will be withdrawn by an automatic valve arrangement also operated by floats, the waterconnections being such that the water which escapes from one tank will-pass to the next below, and is again used there.

The invention is\il1ustrated in the accompanying drawings, in which Figure 1 is a sectional view illustrating the motor, and Fig. 2 is a detail in section of a valve.

Referring specifically to the drawings, 6 indicates a primary er accumulating reservoir or tank, which may be of any desired size, and which may be supplied with water from any suitable source, such as a stream or spring. This discharges through a pipe 7 into a main supply tank 8. This tank 8 regulates the supply of water to the main or power tank 18. Its dimensions are such that it will contain an amount of water just sufiicient to fill said main tank, such water being supplied to the latter in a manner to be hereinafter described. The pipe 7 has therein a valve 9, connected above to a float 10 which works in a small tank 11 located beside the reservoir 6.

12 indicates a bent pipe having ascending and de scending legs connected between the pipe 7 and the tank 1l, and 13 indicates an outlet pipe from the tank, having therein a check valve 14 which prevents water from backing up through the pipe 13.

15 is an air inlet pipe to the top ofthe tank.

The valve 9 is connected below to a lever or werking beam 16 which is in turn connected to a float 10 in a tank 1l connected to the tank 8 by a bent pipe 12 and an outlet pipe 13 having therein a check valve 14. The capacity of the main supply tank 8 is substantially equal to the capacity of one et' the motor tanks hereinafter described, with its appurtenant tanks and water connections.

The main supply tank 8 is connected by a pipe 7 to an'inlet 17 into the bottom of one of the motor tanks 18 containing the motor floats 19. The pipe 7 has therein a valve 9a which is connected above to a float l0b in a casing 11b located beside the main supply tank 8 and connected thereto by a bent pipe 12b and outlet pipe 13b having a check valve lll". The valve 9 is also connected below to a lever 16, and fioat 10c in a tank 1le having connection with the tank 18 by means of a bent pipe 12c and outlet pipe 13C with check valve 14C.

A succession of tanks may be connected to the pipe S, as shown, each tank having float mechanism controlling the valves above and below the same and operating to alternately open and close the same, such valve connections and operating means being duplicated all down the series or battery of tanks.

Loose links 20 are interposed in the valve connections with the floats 10, 10, etc. to allow the drop of said fieats without affecting the valves. The valves 9, 9, etc., are opened by the tanks above the same and closed by the tanks below the same. One of the valves is shown in detail in Fig. 2, being of the gridiron type, -to give a large opening with small movement.

In operation, when water rises in the tank 6 tothe crown of the bent pipe l2 the water flows through said bent pipe into the tank 1l and lifts the float l0. Said float pulls up and opens the valve 9. This allows the water to flow from tank 6 into the tank 8 until it reaches the crown of the bent pipe 12. It also empties the tank 1l through the pipe 13 and allows the float to drop. When the Water reaches the crown of the bent pipe 12 it flows through the bent pipe and fills the tank 11 raising the float 10 and by means of the reversing lever 16 pulls down and closes the valve 9, shutting off the supply. At the same time the water `rises and flows through the bent pipe 12b and by similar operation of the float 10b lifts and opens the valve 9, allowing the water to flow into the tank 18. This lifts the float 19. Water flows into the tank 18 until it reaches the height of the crown or' the bent pipe l2c through which it then flows inte the tank 11C and by means of the float 10c and its connections closes the valve 9, and at the same time water flowing through the bent pipe 121 will by similar connections open the next lower valve 9" and empty the tanks 18 and 11. And so the operation is repeated down the series of tanks. The floats are nearly as large as the tanks so that but little water is needed to operate the same, and the water may be used repeatedly by the addition of tanks at a lower level. In the embodiment shown the up and down motion given the floats lis utilized to operate the pistons of air pumps 21, which is a convenient way to utilize the power developed.

The vent pipes 15 are advisably of a height equal to the height of the tanks beside which they stand, so that there will be no waste of water therefrom. The crowns of the bent pipes are just below the tops of the tanks, so that the valves will be operated before the tanks run over. The nal receiving tank, indicated at 18, is merely to operate the final valves, being connected thereto by a lever 16b operated by a float valve tank in a manner similar to that above described.

What I claim as new and desire to secure by Letters Patent is:-

l. A hydraulic motor comprising a main tank having valved inlet and outlet pipes, a float in the tank, minor tanks located beside said tank and having iloats therein, inlet and outlet pipes connecting the main and minor tanks, connections between the floats in the minor.' tanks and the valves in the inlet and outlet pipes respectively, to operate the latter, means to open the valve in the inlet pipe, and means to close the valve in the outlet pipe.

2. A hydraulic motor comprising` a main tank having a powen iloat therein, a supply and outlet pipe connected te the tank, inlet and outlet valves in said pipe, minor tanks connected by inlet and outlet pipes with the main tank and having therein floats connected to and adapted to move said valves respectively one way, and means to move each valve the other way.

3. In a hydraulic motor, in combination, a succession of tanks one of which has a power float therein, a supply pipe connected from each tank to the next, a valve in the pipe between successive tanks, minor tanks having therein iloats connected to said valves and receiving their supply from the main tanks, each valve being connected to a float of an upper and a lower tank, to respectively open and close the connection between the main tanks.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE MONO LYNCH.
